JAMES F. SPENOE, OF WILLIAMSBURG, NEW YORK.

IMPROVEMENT IN REVOLVING CONDENSERS.

Specification forming part of Letters Patent No. 54,428, dated May 1, 1866,

To all'whom t may concern:

Beit known that I, JAMES F. SPENCE, of Williamsburg, in the county of Kings and State of New York, have invented a new and Improved Revolving Condenser; and I do hereby declare that the following; is afull, clear, and exact description thereof, which will enable those skilled in the art to make and use the saine, reference being had to the accompanying drawings, forming part of this speciication, in which- Figure l represents a plan or top view of this invention as applied to a common ily-wheel. Fig. 2 is a side elevation of the same as applied to a propeller. Fig. 3 is an end view of the propeller with the condensing attachments.

Similar letters of reference indicate corresponding parts.

This invention consists in the use of a condenser, in combination with a steam-engine, said condenser taking the place of the 'tly- Wheel of the propeller, and the piston of the engine is relieved from all, or nearly all, backpressure. v

A represents the fly-wheel of a steam-engine, which is mounted on a shaft, B, to which a revolving motion is imparted by the action of a steam engine, the piston rod of which y connects with a crank secured to the end of a shaft, B, as shown in red outlines in Fig. l, or in any other suitable manner. The rim of the liy-wheel and its arms are hollow, and the shaft B is also hollow and provided with a Instead of passing the exhaust steam into the hollow rim of a fly-wheel, it may be passed into pipes attached to the wings of a propeller, or said wings themselves may be cast hol-A `as to admit the exhauststeam to the propeller. On reaching the blades of the propeller the steam will immediately condense, and by the action of the centrifugal force it will be thrown out, thus forming a partial vacuum, whereby the piston will be relieved of a large percentage of the back-pressure.

l t is obvious that, instead of using the ilywheel or propeller as the chamber for receiving the exhaust-steam, a separate drum might be used, said drum being secured to a suitable hollow shaft which receives a revolving motion from the steam-engine and I do not wish to confine myself to any particular form of my revolving condenser, neither do I wish to be restricted to any particular place for putting the same up.

What I claim as new, and desire to secure by Letters Patent, is-

A revolving condenser constructed and applied, in combination with a steam cylinder, substantially in the manner herein described, for the purpose specied.

The above specification of my invention signed by me this 11th day of October, 1865.

A JAMES F. SPENCE.
